Abigail Nussbaum thinks the recent Battlestar Galactica mini-finale would have been good, if not for the following:

“With very few alterations, many of Battlestar Galactica‘s
episodes during the second half of its second season and the entirety
of its third season could be jettisoned, and the result would not only
make sense as a story, but would probably be tighter and more compelling.”
